Patented Nov. 19, 1929 EJNETEE STATES PATENT oFFicE JOHN P. WEIS, OF NYACK, NEW YORK, ASSIGNOR TO METROPOLITAN SEWING MA- CHINE CORPORATION, OF NYACK, NEW YORK, A CORPORATION OF DELAWARE COMBINED TOP-FEED AND RUFFLER MECHANISM FOR CYLINDER SEWING MACHINES Application filed February 17, 1927. semi No. 168,886.

This invention relates to sewing machines more particularly to cylinder arm machines in which the work is fed along the arm or cylinder in the direction of its length, although the invention can be adapted with slight changes to feeding the work around the cylinder, an object of the invention being the provision of an improved driving mechanism whereby top feeds, rulflers, trimmers. ornamental stitch mechanisms and the like, can be operated from above instead of below the line of travel of the work to be stitched.

Another object of the invention is the provision. of a top feed or rufiling mechanism simple in construction and practical in operation at high speed and which is so positioned as not to interfere with the hands of the operator when guiding the work to the stitching mechanism, and which can also be readily attached to any of the Metropolitan sewing machines now in use whereby users of such machines can keep their equipment up to date.

Another object of the invention is the proision of a top feed and rufiling mechanism and driving means therefor so organized and positioned with respect to the stitching elements that its operation at high speed, both as to rapidity of motion of the machine elements and the rapidity of production of work turned out by the machine, is obtained and its effectiveness is materially increased.

In the drawings accompanying and forming a part of'this specification, Fig. 1 is a side view of a cylinder machine showing this improved driving means connected with the main shaft of the machine and the top feed and milling mechanism. The view also shows parts of the foot lifting and top feed lifting mechanism and the foot treadle there-- for; F L 2 aperspective view of the ma chine showing the top feed and the driving mechanism therefor and it also illustrates the binding attachment for guiding a folded binding to the stitching mechanism; Fig. 3 is an enlarged side view of the, machine with the top feed applied thereto. The full line position of the parts shows the back top feed while the dotted line position shows the parts reversed to provide a front top feed. The

front and back top feed mechanisms are interchangeable, the change fro-m one to the other can be quickly made by the substitution of but a few parts. The view also shows a rear end view of the binding guide; Fig. 4 is a front enlarged view of the operating parts of the top feed and ruflling operating means; Fig. 5 is a detail of the ruflling blade; Fig. 6 is a perspective detail view of the lifting means for the top feed when operated by the needle drive roc shaft and Fig. 7 is a perspective detail View of the parts for lifting and controlling the up and down motion of the top feed parts and illustrates the manner in which they are connected for operation mechanically and also manually.

Similar character of reference indicate corresponding parts in the several figures of the drawings.

Before explaining in detail the present improvement and mode of operation thereof.

I desire to have it understood that the invention is not limited to the details of .construction and arrangement of parts which are illustrated in the accompanying drawings, since the invention is capable of other embodiments, and that the phraseology which I employ is for the purpose of description and not of limitation.

In the preferred form thereof shown a work table 1 supports the base 2 of a cylinder sewing-machine. The trunk3 of the machine comprises a hollow rectangular stand-- ard of the well-known Metropolitan sewing machine, in which is housedthe geared pump for automatically oiling the entire machine and also all of the working parts of the looper, bottom feed mechanism and the needle driving means. Theopening at the back of the trunk is closed by a cover 4:. The over-- hanging arm 5 terminates in a forwardly and downwardly extending needle bar bearing 6. The looper and bottom feed mechanism of well-known construction operates in the cylinder 7 and this cylinder is secured at 8 to the trunk 3 in some suitable way. The cylinder is provided with a throat plate 9 having the usual feed slots and needle opening and is provided with an end cap 1 0 to cover the looper. The needle 11 is carried by the needle bar 12 which operates in the bearing 6. This bearing is capped with a felt oiler 13 and the top of the needle bar 14: is connected by a link pin 15 to a link 16, the opposite end of which is connected to an arm 17, see Fig. 6 by a pin 18, and this arm is secured to a rock shaft 19 for imparting reciprocating movement to the needle bar and needle. The rock shaft is mounted in bearings 20 and 21 and is operated from a crank shaft and suitable connection enclosed in the trunk of the machine frame so that the rocking of this shaft reciprocates the needle. The arm 17 is adjustably clamped to the rock shaft by screws 22. The needle 11 cooperates with a thread carrying looper ornon-thread carryinglooper accorc ling to the character of stitch to be made or it may cooperate with a lock stitch shuttle and bobbin to make the wellknown lock stitch.

The right hand side wall of the trunk 3 of the machine framecarries a belt guard 23 which is partly open at 24, while the bottom portion 25 is closed to guard thebelt. A combine d hand and belt wheel 26 operates within the overhanging top portion of the belt guard and is secured to one :end as 2 of (a main or crank shaft supported in suitable bearings in the trunk 3 and which operates the various elements of the machine. The opposite end 28 of this crank shaft has secured to it a bevel gear 29 see Fig. .1, which meshes with bevel gear 30 securedto ashaft- 31. These two gears are entirely enclosed in a housing 32 which contain lubricant forlong periods of time. This housing maybe either part of the machine frame casting or in the form of an attachment secured to the frame. The shaft 31 is provided with thrust collars 33 and 34Cv to control theend movement of the shaft. Collar 33' isagainst the bearing of the housing 32 while collar 34 is against the bearing of a housing 35. This housing 35 carries two bevel gears 36 :and 37 and also provides a chamber for lubricant. This housing 35 is in the form ofa bracket casting and has bearings 38 and 39, see Fig. 4, which are-connected by a web'casting .40, a portion of which is attached 'as .at 41 to the overhanging-arm 5, see Fig. 3,while a downwardly depending portion is'attached as at .42 to the forward bearing 21 of the needle drive rock shaft 19, see Fig. 4. This provides a substantial way of connecting this bracket to the forward end of the overhanging arm -5 and fixes its relative position to the needle operating mechanism in a desirable manner.

The mechanism so far described can be readily attached'to any of the Metropolitan sewing machines now in use. As the trade requirements are continually changing, by having the mechanism designed so that it may be applied to any machine now in commercial use,.a considerable advantageis offered to the 7 users of the machines in that they can keep their present equipment up to date by applying to it new devices as conditions require.

A horizontal shaft43 parallel to the crank shaft 28 and operated therefrom by the bevel gears and the shaft 31 rotates in the bearings 38 and 39 directly over the needle bar of the machine. This shaft is provided with a slotted disc 4a having an adjusting screw 45 to provide adjusting means for the adjustable crank pin 46 which carries one end 47 of a connecting rod 48 provided with right and left threads the ends for adjustment. The lower end of this rod carries a'bifurcated connection 49 fitting .over the end of a bell crank lever 50, and connected thereto by a link .pin 51. The lever 50 is pivotally supported at 52 by an extending bracket 53 secured to the needle bar bearing as at 54:. This bracket may extend to the rear for the pivot 52 or extend to the front as shown in dotted lines 56 to carry the pivot 55, see Fig. 3. The dependingar1n57 of the bell crank lever 50 is connected by a pin 58 to a link 59 pivoted at60, to the bar of a top working attachment or instrument-ahty, shown as a top feed or ruifler, and therefore, for brevity, designated herein as a feed bar 61, which has adjustably secured to it at 62 the shank of a top feed dog 63. This feed dog has the usual four motions imparted to it so as to co-act with the bottom feed in a step by step motion to clamp the work, feed it along stitch by stitch, lift- .up and move forward to clear the work at each revolution'of the machine. The means just described imparts the forward and backward motion to the top feed, Whether it be operated in front or in the rear of the needle. By adjusting the crank 47 the stroke of the feed may be regulated so as to have the same movement as the bottom feed or it may be adjusted so as to have a movement greater or less than the bottom feed so as to feed the top ply of work a little slower or faster than the bottom ply. This is of particular importance when operating a ruflling blade suchas indicated at 64. Fig. 5. This ruftlinqblade is attached at 65 to a swinging block 66 pivoted at 67 to an adjustable clamp 68 secured to the feed bar 61. The rear end of this pivoted block has connected to it one end 69 of a spring 70, the other end of which is .connected to the feed bar as at 71.

The operation of the bar 61 may be arranged so as to merely have the in and out motion to feed the work in a ruffled form to the needle. By means of the spring 70, the free end of the rufliing blade is held in contact with the goods so as to drag back over it andthen on its movement toward the needle the goods is caused to fold upon itself in a ruflled or plaited manner. There are however some kinds and characters of ruflled work where a semi-rigid ruflling element is desirable. In such instance the ruflling blade has four motions in and out, up and down, similar to a feed dog in its action on the work.

The rise and fall of the top feed dog 63 is obtained as follows: The shaft 43 has secured to it an eccentric 72. Operating on this eccentric is a connection 73, see Fig. 2. This connection 73 terminates in a spring and plunger carrying barrel or cylinder 74 to give resilient pressure to the top feed on the work so as to compensate for varying thicknesses of work and also enable it to feed over uneven portions such as seams and the like. The spring barrel 74 is bored to receive the reduced end 75 of the plunger 76. The coil spring 77 surrounds the reduced end of the plunger and has one end against the top wall 78 of the barrel and the other end against a shoulder 79 of the plunger to give downward pressure to the plunger which is provided with a cross pin 80, see Figs. 3 and 7, for limiting downward movement of the plunger. This pin has its two ends projecting through slots 81 in the side Walls of the spring barrel. The lower end of the plunger is pivoted as at 82 to the bifurcated end of a swinging lever 83, see Fig. 7, which is connected immediately back of this pivot 82 to the upper end 84 of the feed bar 61. This feed bar is so shaped as to reach up through a slot the casting of the overhanging arm just in the rear of the needle bar bearing 6 and also through a slotin the extended part 53, of the bracket 54 and which thus guides the feed bar in its movements so'as to limit side shake or play; The arm 83 is pivoted as at 85 to the side of a guide block 86 carried by the presser foot bar 87 and this guide block is provided with a rearwardly extending portion 88, see Fig. 7, fitting into and guided by the bifurcated end of a presser foot lifting lever 89 for lifting the presser foot, and the top feed when desired. The extending part 88 of this guide. block 86 prevents axial or turning movement of the presser foot bar 87 and insures a steady sup-' port for the arm 83 and the parts connected to it. The side walls of the presser foot lever 89 also straddle the presser foot bar 87, as at 90 and this bar 87 operates in bearing 91 for up and down movement. The lower end of this bar 87 has attached to it as at 92 the shank of a presser foot 93, which operates close to the needle to strip the work therefrom as the needle rises and to clamp the work to the throat plate while the needle is descending. It is lifted above the work while the top and bottom feeds are feeding the work.

For certain kinds of work, the operation of this presser foot during a period of each stitching cycle is desirable, while on other kinds of work-this is not necessary, as, a light pressure suflicient to strip the work from the needle may be all that is necessary under some working conditions. In the present instance however an up and down movement is impartedto the presser foot and the presser bar during a period of each stitch cycle. This movement is in timed relation with the other elements of the stitching and feeding mechanism so that such Work as binding sharp cor ners, and irregular forms of all kinds can thus be done with the greatest ease while the machine is operating at high speed. To operate this presser foot two forms of means are provided, one comprises an eccentric 94 carried by the shaft 43. This eccentriccarries a connection 95 provided with a rod 96 having a ball socket joint 97 at the other end. The ball fitting this socket is integral with a lever 98 pivoted to the bearing 21 as at 99. This lever swings on the pivot 99, the forward end thereof being bifurcated to straddle the presser foot bar 87 as at 100, see Fig. 4, with this end of the lever in contact with an adjustable collar 101 secured to the bar 87. By adjusting this collar up or down or by changing the length of the connecting rod 96 different degrees of lift may be given to the bar 87 so as to lift the presser foot 93 higher or lower as may be desired. This lifting motion of the presser foot is against the downward pressure of the presser spring 102, see Figs. 2 and 3, the pressure of which is regulated by a screw 103. The rear end of this spring rests on a stud 104 while the forward end rests on the extending end 88 of the guide block 86.

From the foregoing it will be seen that the lifting motion of the top feed 63 is entirely independent of the lifting motion given to the presser foot 93, as the lifting motion of the top feed-is obtained from the eccentric 72, by reason of its plunger connection 76 with the arm 83 swinging on the pivot 85, while the up and down motion of the presser foot is obtained from the eccentric 94 through its rod connection 96 with the lever 98, each of which has independent spring pressure by means of the springs 77 and 102.

The other means for lifting the presser foot is obtained without the use of the eccentric 94 and the connection 95, see Fig. 6, by changing the location of the pivot 99, Fig. 4 and locating it as at 99 in Fig. 6 and employing a two armed lever, one arm having a bifurcated end 105 overlapping the presser foot bar 87 and the other arm 106 extending rearwardly underneath the hub of the needleoperating arm 17. Attached to this needle operating arm is a slotted plate 107 recessed into the face of the hub and held in place by a clamp screw 108. This plate has a curved camming portion 109 reaching underneath the hub so as to contact with the arm 106 of the lifting lever. The arrange ment of the parts is such as to give a lifting motion to the bar 87 as the needle rises and lowers the bar as the needle descends, permitting a dwell or idle period of motion of the lever while the needle is in the work.

By adjusting this plate 107 across the face of the arm, permitted by the clamp screw 108 passing through the slot in the plate 107, the time relation as well as the extentof movement given to the lever maybe regulatedand since the lifting of the presser foot must in practically all cases be coincident with the actuation of the needle, this arrangement offers a very simple means for manipulating the presser foot.

To lift the top feed mechanism including the presser foot manually, I provide a floor treadle 109, see Fig. 1, and a chain 110 connected to a rod 111 carrying a spring 112 and an adjusting collar 113 to carry the weight of the treadle rod and exert an upward pressure to prevent these parts from vibrating while the machine is in operation. This rod 111 isconnected as at 114:, see Fig. 2, to the rear end of the lifting lever 89. This lever 89 is pivoted at 116 to the overhanging arm 5 of the machine frame and has its forward end in engagement with the guide block 86 of the presser foot bar 87, see Figs. 3 and 7. This permits the lifting of the top feed and presser foot for starting or removing the work when making adjustments on the machine.

The organization of the working parts of the machine is such as to enable the stitching of all kinds of abrupt turns, corners, curves, etc, without the manual operation of the lifting parts, as the manual lifting is only required for the hereinbefore stated purposes.

While the machine shown in the drawings is organized for binding, it is not limited to that kind of work. To illustrate the binding of shoes and the like I employ a binding folder 11? and a right angle binder 118 located as closely as possible to the needle, see Figs. Qand 5.

It will. be observed that the end cap 10 of the cylinder arm 7 is made very short so that the fingers of the operator can be positioned as close to the needle as possible, which olfers considerable advantage in stitching curved and other irregular forms of work.

A cylinder arm machine offers many advantages in various stitching operations on shoe uppers and other circular or closed portions of wearing apparel in that numerous articles can be passed along on the cylinder until the entire cylinder is loaded with work and then the work may all be removed at one time, thus saving considerable interruption for this permits almost continuous operation of the machine, and moreover, effects considerable economies in binding, stay strip, sewing threads and other materials used in the stitching operation in that they can be run very close to one another, thereby avoiding waste portions of the sewing materials between the stitched articles. With the present day necessities for economies in manufacture these seemingly trivial details amount to a considerable item when the days work is taken into consideration.

mismaes it is readily adapted for use with trimming devices, perforating mechanisms,ornamental stitch mechanisms and various other auxiliary sewing machine attachments and devices such as thread take-ups and in fact is easily adapted for use with quite a variety of mechanisms for performing a wide variety of.stitchingoperations.

It is to be understood that by describing in detail herein any particular form, structure or arrangement, it is not intended to limit the invention beyond the terms of the several iclaims or the requirements of the prior art.
